All Ya Need To Know About Sound
Well done and I always like an educational presentation like this that summarizes the material at the end. Good film even if it lacks the humor of campiness and naivate and deals with a mundane subject.
I totally forgot that sound travels better through things denser than air. But it makes sense.

"Nature of Sound" nothing special
Average science film for youngsters. Nothing creative or special about this one.

Simpleton Coronet production about sound basically takes the Mr. Science approach to things, but the kid actor in the piece is just so annoyingly chipper about the whole thing that the whole science thing is distracting ovwer what he could say next.
After feeling a vibrating bell with a block of wood and string that he just HAPPENS to have in his pocket, the boy visits his cousin at the college and learns all about how wonderful sound is. "Gee, I sure can have a lot of fun meauring the distance of sound!" he chirps at one point. I wonder if he has any friends.

Basic audio physics...you know, for kids
Always carry a wood block on a string! You never know what it will teach you about The World Around You (tm). Little Jimmy Foster gets the snot scared out of him by leaning against a railroad crossing bell. And when he hangs his wood block next to the vibrating bell...hey, that gets him thinking...how does sound work, anyway? Helpful pal/ham radio operator Phil Hanson teaches him all about the way sound works, by describing and performing a few basic science experiments, including a keen oscilloscope and an ocarina. Alas, Phil has to go and confuse things by bringing up the speed of light, but Jimmy still thinks he can have "a lot of fun measuring the distance of things by sound." Watch for Phil to misspell the word "Characteristics." And that's that.
